Patachou is an over-rated local chain with average food that draws people because there isn't much else . Sort of Like Zingerman's in Ann Arbor (but Patachou has less attitude ).
I agree Napolese is good (the Penn location is the best of the 3)
The Beard awards(for the non individual categories anyway ) have not been a consistent indicator of quality for a couple of years now .
Oakley's is very inconsistent -one day above average verging on good the next way below par
But it all depends on what you are looking for .
Try Bluebeard near fountain square if you are looking for an interesting eclectic but good meal . the wait can be long though .
If you want a good breakfast near the ICC, I would go to Yolk. Also a chain but the food is solid. Still expect to wait, though. If you are into the food scene, you can try Milktooth for breakfast/brunch and see what you think. They are usually not super busy on the weekday mornings and it's far enough away from the ICC to not get a ton of the GenCon crowd. I think grbrt may actually have been the person I had this discussion with previously on the forum, but I thought it was good but not mind-blowing, and the service was super-slow.
I would like to try Oakley's, but it's far enough away from downtown nobody else in my party is interested in making the trip. I think the JBF website is a solid starting place overall to find good food -I definitely refer to it for reccs myself- but I agree that sometimes I've been thoroughly underwhelmed. You just gotta get out there and decide for yourself. :)
